I stand by my statement; the experience is true. (the 750 was a very highly rated PSU when I had the problem, and I did not have much on my system but 2 hard drives, BDROM and a few fans, sound card and higher end graphics card). The higher watt PSU also does not draw more power inherentlly. I've got a Zalman fan controller/temp monitor/power meter that even the psu plugs into so I get a continuous readout of the power drawn off the cord in the wall from everything in the case, including mobo, fans, PSU etc and it is accurate with a KillOWatt meter.)
I get that this is above the suggested rating and some folks may do fine at the recommended wattage. But I sure wish someone had warned me; I found out after the fact. Get what you want; I'm only offering suggestions based on my actual experience.
Let me amend this response for clarity - I don't know that you'll use 1000W unless you add a second video card, but what I'm really saying is get the best Quality PSU you can, and the extra overhead for me put me into a higher category of PSU - more robust with cleaner rails and more isolation, and rated to maintain that under greater load. I shouldn't have needed to upgrade the PSU I had, but when I did.... no more problems. I'm guessing for whatever reason the power draw of my graphics card (even during normal non-gaming usage) somehow affected the bias voltages that feed the hard drives... which is why they became nonfunctional. This user has a nice graphics card in his setup. I'd spend a few more bucks on the best quality PSU he can get to protect that graphics card, and the rest of his computer.
